Cam-type continuous punching mold

Abstract

The invention provides a cam-type continuous punching mold. The cam-type continuous punching mold comprises a molding module, a cutoff module and a rotating shaft module, wherein the molding module isa group of female molds which are symmetric forward and backward; molding curved surfaces having the same shape are arranged on the opposite surfaces of the female molds; fixed cutters are arranged on the side surfaces of feeding ends of the molding module; the cutoff module comprises a sliding block which slides forward and backward; a sliding cutter is arranged on the sliding block; the slidingblock is driven by a pushing device; the rotating shaft module comprises a punching rod; the end surface of the punching rod is a circular arc surface; and the punching rod is rotatably arranged on arotating shaft driven by a rotating motor. The cam-type continuous punching mold can realize the punching of a sheet workpiece to be machined after the rotary punching rod rotates, and can realize the continuous feeding, cutoff, punching and blanking.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a continuous stamping die. Background technique [0002] Stamping is a forming processing method that applies external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation, thereby obtaining workpieces of required shape and size. The mold used for stamping is called stamping die, or punching die for short. When the existing stamping die is in use, the staff first needs to position and install the workpiece to be processed, and then the stamping operation can be carried out; the workpiece moves during stamping, which causes the stamping size of the workpiece to fail to meet the requirements, and even causes the phenomenon that the workpiece is scrapped. For the stamping process of a large number of sheet workpieces, the staff need to repeatedly position and install the workpieces, and each stamping process can only stamp a single...

AI Technical Summary

Problems solved by technology

For the stamping process of a large number of sheet workpieces, the staff need to repeatedly position and install the workpieces, and each stamping process can only stamp a single workpiece, which is not conducive to saving the time required for stamping operations, nor can it improve stamping efficiency

In addition, during the stamping process of the stamping die, the punch will reciprocate during stamping, so it can only perform the demoulding operation of stamping parts during the reset movement process, which prolongs the time required for one stamping and is not conducive to improving stamping efficiency.
